Haitai Crane’s portable gantry crane delivers 1-10 ton full overhead lifting capability without permanent infrastructure. Designed for workshops, maintenance bays, construction sites, and field service operations, the crane assembles without special tools, relocates on caster wheels, and adjusts to match the exact span and height your job requires. From a 1-ton lightweight steel frame to a 10-ton heavy-duty gantry, the range covers the full spectrum of light-to-medium industrial lifting.
A portable gantry crane is a mobile lifting system built around a steel frame supported by four detachable legs. These four legs can be bolted together without tools, allowing quick assembly, relocation, and disassembly. Therefore, this flexible portable gantry crane is ideal for workshops, warehouses, and temporary job sites where a fixed crane would be impractical.
The overhead bridge runs on rails or rollers, allowing smooth horizontal travel. A hoist (electric hoist, hydraulic hoist, or manual hoist available) raises and lowers loads up to 10 tons with a usable span of 2‑16 m and a lift height of 2‑12 m.
Configurations allow users to adjust leg length, spread, and accessories such as spreader beams or trolleys, making the portable gantry crane ideal for occasional lifts where a fixed crane would be impractical or costly.
Users can choose custom steel‑section sizes, leg configurations, and accessories such as spreader beams or trolley systems to match specific workflow requirements. This flexibility, combined with tool‑free assembly, provides a safe, efficient, and adaptable solution for a wide range of material‑handling tasks.

Haitai portable gantry cranes have six key features in structure design, customizable parameters, and high working compatibility.
◆ Bolt-Together Frame — No Welding Required
All structural connections use high-tensile bolted joints (Grade 8.8 fasteners). Assembly requires only standard spanners — no welding equipment, no certified welder, no hot-work permit. Typical assembly time: 2 technicians, 1–2 hours depending on span.
◆ Adjustable Span and Height
Telescoping leg and beam sections allow span and height to be set at multiple fixed positions within the rated range. Adjustment is tool-free on adjustable models. Locks positively at each setting with through-bolt and safety pin.
◆ 360° Swivel Casters with Brake
Heavy-duty polyurethane casters allow the crane to be repositioned by hand without load. Individual wheel brakes lock the crane at the working position. Caster load rating matches crane capacity at rated span with standard safety factor.
◆ Lightweight Steel Option for Easy Relocation
Light-section steel frames on 1t–3t models are designed to minimise dead weight without compromising structural integrity. Leg and beam sections are sized for two-person handling and transport in a standard van or pickup bed.
◆ Modular Sections for Transport
All models disassemble into sections that fit standard van or pickup bed. Models up to 3t are sized to fit a standard van or pickup bed when disassembled. All sections are clearly marked for fast reassembly in the field.
◆ Compatible with Standard Hoists
Bottom flange of the main beam is machined to standard I-beam profile (per BS 4 / DIN 1025), accepting any standard manual chain hoist, electric chain hoist, or wire rope hoist with appropriate hook or trolley fitting.

If you manage a marina, boatyard, or naval facility, you already know the pain: vessels stuck in the water waiting for maintenance, slipways that damage hulls, and cranes that simply weren’t built for boats. A marine travel lift solves all three problems in a single machine. It lifts, moves, and launches vessels safely — without fixed rails, without hull damage, and without slowing down your yard. This page covers everything you need to evaluate a marine travel lift: what it does, where it works, what makes ours different, and the full technical specs. If you are ready to specify a unit, our engineering team responds to enquiries within 24 hours. Product Description A marine travel lift — also called a boat travel lift, mobile boat hoist, or self-propelled boat hoist — is a rubber-tyred gantry crane designed specifically for vessel handling. The portal frame straddles the boat in the water. Polyester slings are positioned under the hull. The vessel is then lifted clear and driven anywhere on land. No rail tracks. No fixed infrastructure. Just one machine that handles haul-out,…
Choosing the right RTG crane supplier impacts your entire port or yard operation. A wrong choice means delays, downtime, and costly repairs. We help you avoid that. As a certified RTG crane manufacturer and exporter, we supply high-performance rubber tyred gantry cranes built for container terminals, intermodal yards, and logistics hubs worldwide. Product Description An RTG crane (Rubber Tyred Gantry Crane) is a mobile overhead crane designed to stack and move ISO containers in port container yards and inland depots.

If you handle heavy containers, steel structures, or oversized industrial cargo — and your site lacks fixed power infrastructure — a hydraulic straddle carrier is likely the most practical solution available. It lifts, travels, and places loads without needing overhead structures, rails, or high-voltage power supply. One machine. Full mobility. Minimal civil works. What Is a Hydraulic Straddle Carrier? The Core Concept A hydraulic straddle carrier is a self-propelled heavy lift vehicle. It straddles a load — lifting from below using a hydraulic spreader or lifting beam — and moves freely across the yard on rubber tyres. The entire lift-and-travel cycle is powered by an onboard diesel-hydraulic system. Unlike electric or cable-reel powered cranes, the hydraulic straddle carrier carries its own power source. This makes it fully independent of yard infrastructure. You can deploy it anywhere your surface can support the wheel loads — no fixed installation required. How the Hydraulic System Works The engine drives hydraulic pumps that supply pressurized fluid to the lift cylinders, drive motors, and steering actuators. All motion — lifting, lowering, travelling, and steering —…
